You're going to love the switch from BB!
These points are coming from my Galaxy Nexus phone.
Android Pros:
-Ice Cream Sandwich is a very slick new OS, with significant improvements over older versions.
-The Gmail app is just awesome.
-The ICS keyboard is big, accurate, and excellent at auto-correcting. Within a week you'll be typing faster than with a physical keyboard.
-I never have my phone tethered to the wall. I have a spare battery and spare battery charger so that I never have downtime and when traveling always have 2 spares ready to go when I'm away from plugs. Spares are just $19.
-The Android GPS with Google Maps and POIs can easily replace a real GPS and is incredible for walking directions.
-4G LTE, faster than your home internet connection.
-Free usage as a wifi hotspot=4G anywhere anytime on your laptop.
-Chrome browser is incredible. And you can switch seamlessly between phone and desktop without losing tabs.
Android Cons:
-Not as many Jewish apps as iPhone. Coming from Palm OS this is my one and only complaint.
